s13 fuse box harness inquire
 

hello everyone, I'm new to the community and I'm also new to the S chassis and the SR20 engine, got rid of my 03' 350Z because I had the chance to get my hands on a very nice s13 coupe sr20 blacktop swap, as I was checking the engine bay I found that the wiring on the eco was not done right and its a very dangerous harness to run as not only it looks like a rat nest, a lot of the cables are cut and taped together and it just a disaster in general, my question is, do I need to replace the chassis harness or the fuse box harness connects to the chassis harness or ECU? or is it a whole piece, I've never done wiring before so I decided to ask you guys with a lot more experience, thank you:newbie:

The ECU is connected to your engine harness. The easiest, simplest solution for someone who has never messed with wiring is to contact Wiring Specialties. They will build you a 100% plug & play engine harness for your SR swap with no cutting/taping/splicing needed. The end result is very clean and factory-looking.

I have an engine harness coming in from them soon, I think I didn’t state my question properly, my question is, is the fuse box harness separate from the body/chassis harness or is it a single unit?

The fuse box harness is part of the chassis harness.

Yeah, and WS still hasn't come up with a full chassis harness yet.

if the chassis harness has been hacked, your best bet is to find a car someone is parting out, offer them $250 for the entire harness, then swap that bish over.

its a pain in the butt, but less of a pain than fixing a bunch of stupid mistakes made by a previous owner.

just make sure the donor car has all the same options as yours (power windows, ABS, a/c, etc)
